Mango has been reported to have extensive diversity due to alloploidy, outbreeding, repeated grafting and phenotypic differences arising from varied agro-climatic conditions in different mango growing regions [3].
However, complex species relationships within the genus suggest that autoploidy, alloploidy, interspecific hybridization, and genetic introgression between related populations have all contributed to the evolution of common octoploid smooth bromegrass (Armstrong, 1985).
Apart from the tedium of this method, the best and most simple proof of alloploidy is the occurence of 3n univalents in crosses with different diploids with known genomic constitution: "Auf diesen Wegen kann der Genomanalytiker innerhalb einer Allopolyploidie aufweisenden Gattung oder, wenn wir die Gattungsgrenzen des Systematikers uberschreiten, innerhalb einer alloploide Beziehungen aufweisenden Artsgruppe ihren 'Genomschatz' feststellen" (Kihara, 1930: 267).
